E10 petrol replaces E5 as standard unleaded and will be sold next month – but some vehicles are incompatible and this could drive costs up


    Not all gasoline vehicles are E10 compatible – so check yours

    According to the Ministry of Transport, around 95% of gasoline-powered vehicles on the roads can use E10 today. This includes all cars built since 2011 and most cars and motorcycles made since the late 1990s.

    But government analysis has shown that up to 600,000 older cars are incompatible. These include some popular models like the MG MGB, Morris Minor, and Rover 25, according to the RAC Foundation’s auto research group. The government warns that the following types of vehicles in particular could be affected:

    • Classic and older vehicles
    • Some specific models, especially from the early 2000s
    • Some mopeds, especially those with a displacement of 50cc or less

    If you don’t know if your car, van, motorcycle or moped is compatible, you can Use the free checker on the Gov.uk website – however, be aware that many vintage car manufacturers are not listed in the tool so you may have to contact the manufacturer directly to inquire.

    For those with incompatible vehicles or for those who are not sure if they are affected, you will need to upgrade to the more expensive “super” E5 (97+ octane) gasoline that most garages still have in stock. But that costs more; With an average of 146 pence / liter, super unleaded is currently around 11 pence / liter (8%) more expensive than the previous standard unleaded and the new E10 unleaded, based on the latest figures from the RAC.

    Failure to switch to premium unleaded gasoline, and prolonged use of E10 gasoline in an incompatible vehicle, can damage it over time, as the extra ethanol can corrode certain metal parts and cause problems with other materials used for gaskets and gaskets in the fuel system be used. It shouldn’t be a problem if you fill up with E10 instead of E5 fuel once or twice.
